Mickey’s beloved pal Pluto made his film debut in 1930 as a nameless bloodhound in “The Chain Gang.” Later that year he played Minnie’s dog, Rover, in “The Picnic.” He was officially known as Mickey’s dog, Pluto, in “The Moose Hunt” (1931). Pluto starred alongside Mickey in numerous shorts, including the Academy Award-winning “Lend a Paw” (1941), and later teamed with Donald Duck on a number of shorts. Pluto made his feature film debut in 1988’s “Who Framed Roger Rabbit?”
